Projector Screen

Projector screens are basically installations, which are useful for the purpose of displaying videos, images and presentations from a projector, to an audience. A projector screen’s conventional material is made of fabric or vinyl coated with substances, which are reflective in nature.

When you want to buy a projector screen, the size is one of the most essential factors to consider. The screen size depends on the model of the projector you use. This happens because the size of the image and the brightness of the projector are inversely proportional.

Explaining further, when you increase the size of an image, the image’s brightness reduces, given all other factors are constant.

Depending on the size of your room, it is advised that the underneath of your screen does not touch the floor, as it could hinder viewing. It is essential that limitations such as these prompt you to make the right decision when purchasing a projector screen.

Projector screens have a broad range of conformations. However, there are two general types: The permanent screen and the portable screen.

How to Determine Projector Screen Size?

Hence, before you learn how to determine the screen size of a projector, you need to consider the aspect ratio of the projector. This indicator should give you a worthy starting point for a projector screen size.

Movies in the widescreen format require a dissimilar setup when compared to a presentation, which has complicated data in a meeting room.

In determining a projector screen size, one of the ultimate considerations has to be the enjoyment of your audience stands after each viewing experience. Harry Potter binge watch, anyone?

Screen Size By Ratio

One of the most vital means of acquiring the ideal screen size for viewing purposes is to ensure that the screen height ratio is correct. For the 4:3 size, it is required that the height of the screen is a minimum of one-sixth at the distance from the farthest away chair to the screen. This size is ideal for venues which are very large. If conference rooms or classrooms employ of the 4:3 video, the screen size is required to be quarter the distance from the furthest away chair.

Determining Steps for The Size of A Screen

The very first step would be to calculate the distance of the projector from the wall

Next, calculate the tangent of the angle, which would determine the offset angle of the projector

Multiply the distance of the projector from the wall by the ratio

The documentation of the projector reveals the offset percentage of the projector. Minus 100 from the percentage

From the ratio result gotten in the third step, divide the ratio by the result gotten in the fourth step

Multiply the aspect ratio of the projector by the height. The achieved result would be the least width of the screen

There is an important specification for projectors, known as throw ratio, which is determined by two factors namely:

The throw distance, which is basically the distance of the projector from the screen

The width of the screen

As earlier mentioned, the first step in purchasing a projector, is the screen size and the throw distance. Once these two factors have been sorted out, then you can be sure to narrow down your basis for selection to a few. It’s easier than voting for most presidential elections, for sure!

Sometimes, your space could offer the opportunity for mounting the projector at any given point in the ceiling. In turn, you have the luxury of technically choosing any projector you want, since you’ll want to mount the projector very close to the screen in a comfortable manner.
